Title
=======
Measuring intact protons at the LHC: From the odderon discovery to the search for axion-like particles
 
Abstract
==========
In the first part of the talk, we will describe the odderon discovery by the TOTEM and D0 experiments. The analysis compares the p pbar elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV. The two data sets disagree at the 3.4$ sigma level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering, leading to a combined significance larger than 5 sigma.
In a second part of the talk, we will describe the perspective on the search for quartic anomalous couplings and axion-like particles using tagged protons in the final state, leading to sensitivities to beyond standard model physics that improve by 2 to 3 orders of magnitude on the coupling. We will finish by decribing briefly the ultra fast silicon detectors for timing measurements as well as for medical and cosmic ray physics applications.

Probing quantum foundations at subnuclear scales

Abstract: The standard model of particle physics is founded on the basic rules of quantum mechanics. One way to seek "new physics" is to question some of these rules. In my talk I will explain how to do it in a rigorous way, using the recent development in quantum information. Along with the conceptual scheme I will discuss the challenges for its empirical implementation in the subnuclear regime.

Elementary example of exact effective-Hamiltonian computation
 
We present an exact computation of effective Hamiltonians for an elementary model obtained from the Yukawa theory by going to the limit of bare fermions being infinitely heavy and bare bosons being at rest with respect to the fermions that emit or absorb them. The coupling constant can be arbitrarily large. The Hamiltonians are computed by solving the differential equation of the renormalization group procedure for effective particles (RGPEP). Physical fermions, defined in the model as eigenstates of the effective Hamiltonians, are obtained in the form of an effective fermion dressed with a coherent state of effective bosons. The model computation illustrates the method that can be used in perturbative computations of effective Hamiltonians for realistic theories. It shows the mechanism by which the perturbative expansion and Tamm-Dancoff approximation increase in accuracy along the RGPEP evolution.

Zapraszamy na prezentację laboratorium HAL

Data opublikowania 30.04.21 10:15

Zapraszamy na prezentację laboratorium Hardware Acceleration Laboratory, która odbędzie się 6 V wygłoszoną przez Piotra Korcyla. Prezentacja jest zaplanowana na ok. 14:45/15:00.

Hardware Acceleration Laboratory ma za zadanie tworzyć pomost pomiędzy szeroko rozumianymi naukami obliczeniowymi a informatyką, informatyką techniczną i elektroniką odpowiedzialnymi za powstawanie nowych platform obliczeniowych. Mnogość tych ostatnich: CPU, GPU, FPGA, ARM, TPU, neuromorphic jak i wszystkie możliwe ich kombinacje, jak również szybkie tempo rozwijanych algorytmów, w tym tych opartych na uczeniu maszynowym i sztucznych sieciach neuronowych przekracza zwyczajowo kompetencje użytkowników będących biologami, chemikami czy fizykami. Nowa platforma w postaci laboratorium HAL ma być brakującą dotychczas międzydyscyplinarną przestrzenią gdzie możliwe będzie poszerzanie kompetencji związanych z technikami obliczeniowymi oraz wymianę doświadczeń. W prezentacji przedstawię założenia jakie kierowały nami przy współorganizowaniu laboratorium oraz cele jakie sobie stawiamy które zilustruję aktualnie prowadzonymi badaniami.

Title: Study of a lattice 2-group gauge model
 
Abstract: In this talk we discuss a simple model belonging to the class of 2-group gauge systems based on the simplest symmetry group Z_2. Models of this type have independent degrees of freedom associated to both links and plaquettes subject to a certain constraint. We will present in details the  construction of this model, discuss the expected dynamics in different regions of phase space which we will corroborate with numerical results from Monte Carlo simulations.
